ive noticed a couple english cars (jensen healy, and i guess it was an 82 jag xj6) actually have mufflers on the intake. the jag looks particularly weird, as it coned down to a 1" little pipe.

I had a late 70's Ford that had an oil filter on the air cleaner. Weird stuff!



The 92db did sound suspect to me, as the standard of measurement seemed to be to wander around the car with a meter while the driver revved it a little. I am not worried about induction noise since the nature of the race means the stock EFI and airbox will have to be used, no budget for anything "racy". Gotta make power and no money to do it: just my cup of tea. The measurement is from 100 feet at WOT.



At least we can add lightness.



I did have a kind of crazy idea for the muffling. FC chassis. The exhaust pipe(s) would exit into a large volume, like for instance the spare tire well after being suitably sealed, and that volume would have a number of ventholes aimed at the ground. Would it work? Perhaps, perhaps not. I know certainly that the diffusers and the stock exhaust manifold will be in use, which will help tremendously.



quick edit: I was just informed that the exhaust system aft of the manifold/header is free from budgetary restraints. That certainly makes life a lot simpler!

my last fc was really quiet, all i did was have all the holes fixed in the exhaust. lots of room for mufflers....
